APIPA RATUS FOR SORTING HE'IEROGENEOUS MATERIAL.

Patented June 9, 1914.

Application filed March 24, 1913. Serial No. 753,421

To all whom it may concern Be it known that we, DANIEL R. BRYAN andJOSEPH W. BRYAN, both citizens of the United States, residin at Ghatham,New Jersey, and 47 West New York, N. Y., respectively, have inventedcertain new-and useful Improvements in Apparatus for SortinHeterogeneousMaterial, of which the to lowing is a specification.

This invention relates to an apparatus for sorting heterogeneousmaterial, and aims to provide improvements therein.

The invention provides adapted to sorting and delivering to appropriatereceptacles heterogeneous material such as that which makes up therefuses of cities and consisting mainly of ashes, cinders, paper, rags,glass articles, metallic substances, etc. It provides a means of simpleand durable construction, which will not be clogged up by the service towhich it is put and which operates efiiciently to. perform its intendedfunctions. Other features of improvement will be hereinafter set forth.

An embodiment, of the invention is set forth inthe accompanying drawing,whereshows a longitudinal vertical section (with parts in elevation) andFigs. 2, 3, and 4, transverse sections on the lines 22, 3.-3, and 4-4respectively of Fig. 1.

In said drawings, A, B and C, designate a series of rotatable screens,adapted to empty one into another, and D a chute, preferably rectangularin cross section, into which the material passes after being acted uponby the screens.

The screens may able manner and suitable means are provided for rotatingthem. As here shown, each of the screens is provided with a circularrack E, running in grooved rollers F, and meshing with a gear G,connected through bevel ears H to the shaft of an electric motor Thescreens are preferably so proportioned that the delivery end of one fitswithin the receiving end of another, as for instance the delivery end ofthe screen A fits within the receiving end of the screen B, therebyavoiding the formation of an obstruction by the ends of the screen. Thescreens are also Figure 1 preferably adapted to rotate at differentighty-fourth street,

a means especially be. mounted in any suit-- relative s code, and alsoto have the relative spee s varied. The screens will,ordinarily rotateat different relative speeds, owing to. the fact that they areofdifferent diameters, and being rotated by independent electric motors,variation in the relative speeds of rotation may be produced byincreasing or diminishing the speed of opera.

tion, of one or more of the motors.- The first screen where the smallestparticles are sifted out, should preferably receive the greatest speedof rotation; therefore it may be retated at the fastest speed,.and thesucceeding screens at successively lesser speeds.

A casing J is preferab y arranged around the hoppers to confine thecloudsof dust and fine particles produced by the screening operation.The dust is preferably removed from the casing andfor thisurposesuitable means may be rovide As here shown, an'electrically rivenfan 0 is provided, which reduces a current of air in a conduit 72, whichacts by inspiration, through orifices g, r. and s, over each of thescreens and branch conduits t and u, to draw the dust-laden air from thecasing J into the conduit 72 and carry it away, as to a bin orreceptacle U hereinafter referred to. a

The screens A, B and G and the chute D are preferably mounted upon aframe K arranged at a suitable incline so that the material may movethrough the-apparatus un der the influence of gravity. The frame K isfurthermore preferably mounted at one end upon a pivoted bearing L andsupported at its other end uponlifting means, such as a jack M, by whichthe inclination of the parts may be adjusted to the frictionalresistance of the material operated on, which I screens. Materialpassing from the hopper into the, screen A is agitated and the screenbeing provided with small perforations, is y sifted and has suchparticles as partial ashes and other fine particles removed therefrom.From the screen A the material passes to the screen B where it is againagltated and further sifted. The screen B is provided with largerperforations than the vary from various causes, as for inwho sorted isdumped, and which delivers theisame to the series of screen A, and suchparts of the material as small cinders may be removed. From the screenB-the. material may pass to another screen 0 where it undergoes furtheragitation and sitting. The screen C having larger perforations then thescreen B operates to remove the larger particles from the mass. From thescreen C the material passes into the chute D, and a swinging door Padapted to be held in adjusted positions by means of a rack and dog Qmay be regulatin the passage of t e material through t e chute.

The sifted material which is separated by the several screens, fallsinto a series of funnels, R, S and T, arranged beneath the screens,andis delivered into separate bins or compartments U, V and W, where itmay be collected. As the material passes into the chute D it isreferably first acted upon by a vacuum. l hi's vacuum may be, andpreferably is, produced by the inspiration of acurrent of air, set inmotion in a conduit Y, by an electrically driven fan Z, flowing past anorifice a in the upper part of the chute D (Fig. The efi'ect of thisvacuum is to suck up light particles such as paper and rags and deliverthem into a compartment or bin 6 into which the conduit Y empties.

From the point where it is acted upon by the vacuum the material passesto a point Where it is acted upon by an electromagnetic separator, c,the action of which is to sepa rate metallic like from the mass. Asshown.(see Fig. 4) the electro-magnetic separator 0 preferably comprisesa series of electro-magnets 03, 111 front of which moves a belt e,preferably of non-magnetic material, such as an ordinary canvas belt.Pieces of iron attracted by the electro-magnets will be carried to oneside by thebelte through an opening f in the side of the chute D anddropped into a conduit 9 after being moved beyond the zone of influenceof the magnets. From the conduit g the metallic particles are deliveredinto a bin or receptacle h.

After passing the electro-magnetic sepav rator such parts of the mass asremain, and consisting mainly of bottles and particles of glass, will bedelivered througha conduit 2' at the end of the chute D, into a oin orreceptacle is where they are collected, and further separation may bemade if desired; Each of thebins or receptacles U, V, W, b, h and 7a ispreferably provided with a door, through which the contents may beremoved.

rovided for particles such as iron and the m isa door in the chute Dthrou h which access may be had to the interior t ereof.

Means are provided for antisepticall treating the entire mass of refuseas 1t leaves the hopper. This means may comprise a tank an adaptedtocontain a suitable disinfectant t, a pipe y adapted to spray thedisinfectant over the refuse as it enters the first screen. A pipe z isalso preferably provided through which compressed, air

from a suitable source, may be admitted to the tank to force thedisinfectant out through the pipe 3 over the material to be sprayed-While we have illustrated and described one embodiment of the invention,the invention is not to be understood as limited.

thereto, as many changes and modifications may be made therein withoutdeparting from the spirit of the invention.

What we claim is 1. In a machine of the class described, the combinationof a hollow screen member having inlet and outlet openings, means forfeeding material within said member, suction means .fortransverselywithdrawing under-sized material through the Walls of said screen, andsuction means for simultaneously drawing over-sized material longitudinally of the screen member through said outlet.

2. In a machine of the class described, the combination of a tubularscreen having inlet and outlet openings, material within said screen, adischarge chute arranged at the outlet of the screen and in axialalinement with such screen,

suction means for transversely withdrawing under-sized material throu hthe walls of the screen, suction means connected with the dischargechute for simultaneously drawing over-sized material. longitudinally ofthe screen and through the outlet thereof, and a device located betweenthe outlet of the screen and the last-mentioned suction means forregulating .the flowof material to the chute and to the last-mentionedsuction -means.

In testimony whereof, we, DANIEL R. BRYAN and Josnrrr W, BRYAN havesigned our names to this specification in the presence of twosubscribing witnesses, this 20th day of March 1913.
